And, on the framework 20a of above-mentioned lower mould 20, as shown in Figures 2 and 3, guide member 27 is incorporated into the bight upper surface of lower mould 20, the effect of guide member 27 is: when upper die 10 drops on the lower mould 20, upper die 10 is stacked together exactly with lower mould 20.
Shown in Fig. 4 and Fig. 5 a, shelf 30 is used for the support reinforcing parts, and be fixed, so that strengthening part can not move, shelf 30 in accordance with regulations arranged spaced has the U font groove 31 of opening above, this U font groove 31 has the prevention structure that strengthening part 33 can not be moved along its length direction, and its back is connected with transfer unit 30a.
The both ends of strengthening part 33 are inserted and are fixed on the aforesaid U font groove 31, are placed in U font groove 31 the both ends tight of strengthening part 33, so as long as shelf 30 is motionless, strengthening part 33 is definitely motionless.
The U font groove 31 that above-mentioned shelf 30 possesses can be by regulation depth and configuration space, set burial place and the interval of strengthening part 33 in article shaped, namely, be set in position and the height of the strengthening part 33 of burying underground in the article shaped of moulding, set according to the interval of U font groove 31, can keep exactly the interval of the strengthening part 33 that article shaped inside buries underground.
Cut off the lower surface that framework 24 can be attached to up or down by hydraulic cylinder 24a lower mould 20, by the action of hydraulic cylinder 24a, the bullport 25 that possesses by lower mould 20 is in and out of in the cavity 21.
Cutting off framework 24 is arranging on the direction in opposite directions Face to face at cavity 21 inner bottom surfaces of lower mould 20, two to cut off the partition distance of 24 of frameworks identical with the upper die width, and it is large and than retreating the little position of two shelves, 30 partition distance afterwards to be positioned at partition distance than 30 of two shelves.
Simultaneously, adhere to the pressure support plate 26 that cuts off framework 24 for supporting at the sidewall that cuts off framework 24, cut off framework 24 in order to can stably fix when carrying out operations for forming, wherein, this pressure support plate 26 is arranged on the front of shelf 30 and cuts off on the framework 24.
This is for when upper die during to the pressurization of the molten resin of cavity 21 interior perfusions, supports the rear that cuts off framework 24, makes to cut off framework 24 and can not retreat or mobile because of pressure.
Shown in Fig. 6 a and Fig. 6 b, cut off framework 24 as the framework of a certain side laterally or in the longitudinal direction that consists of article shaped, make after aforesaid shelf 30 retreats, cut off framework 24 and be positioned at the space that the shelf 30 that retreats produces, when shelf 30 is advanced, remove and cut off framework 24.Reference numeral 24a cuts off framework 24 and debouches hydraulic cylinder in the cavity 21 be used to making.
As shown in Figure 2, cooling jacket 40,50 is attached to respectively the cooling jacket 40 below lower mould 20, the cooling water of 50 inside above the upper die 10, cooling upper die 10 and lower mould 20 by being circulated in.
On the other hand, for the molten resin article shaped of cavity 21 interior moulding from lower mould 20 demouldings, between lower mould 20 and article shaped, apply air pressure, can easily utilize easily air pressure, the article shaped that attaches cavity 21 surfaces is fetched into outside the lower mould 20.
In Fig. 2, shown upper die 10 be assembled into can oscilaltion by hydraulic cylinder 10a state.Hydraulic cylinder 10a is fixed on the fixed head 11 fixing on the support 12.
Below, with reference to figure to Fig. 1, illustrate and utilize the pallet forming method that as above consists of.
The 1st step 300 is such as Fig. 7 and shown in Figure 16, at cavity 21 interior configuration shelves 30, so that can support reinforcing parts 33.Before the pneumatic cylinder 30b that lower mould 20 both sides are adhered to and then make shelf 30 be disposed at the cavity 21 of lower mould 20 when interior, the operation torque of piston rod 30c that can be by adjustable pressure cylinder 30b is regulated the position of shelf 30, makes consistent that its position of burying underground in wanting the article shaped of moulding and interval etc. and producer require.
The 2nd step 310 is such as Fig. 8 and shown in Figure 16, to the molten resin (MT) of above-mentioned cavity 21 interior perfusion specific thickness, at this moment, the height of molten resin of perfusion is to pour into till U font groove 31 bottoms that possess to the shelf 30, then flattens, and makes the thickness of molten resin be close to identical.
The 3rd step 320 such as Fig. 9 and shown in Figure 16, is fixed in the both ends of strengthening part 33 the U font groove 31 of above-mentioned shelf 30.
The 4th step 330, such as Figure 10 and shown in Figure 16, (secondary) perfusion molten resin makes above-mentioned strengthening part 33 be melted resin (MT) and buries again.At this moment, the groundwater increment of molten resin (MT) need to consider the molten resin number of dropouts that runs off by the resin shrinkage amount that occurs in 21 spans of cavity and the spatial area that is produced by the shelf 30 that retreats, the solidification process and by steam vent 23 etc., and the form thing can the required amount of complete moulding.
At this moment, strengthening part 33 is in the state that all is embedded in fully in the molten resin (MT) that pours into.
The 5th step 340 such as Figure 11 and shown in Figure 16, as being exerted pressure in molten resin (MT) plane of the 1st perfusion and keeping the operation of this pressure, is pressurizeed to molten resin (MT) by make upper die 10 declines with hydraulic cylinder 10a.
During 10 pairs of molten resins of upper die (MT) pressurization, be pressurized to the top that makes upper die be positioned at guide member 27 and get final product.If pressure puts on molten resin, the gas or the hollow bulb that then exist in the molten resin are compressed, and meanwhile, it is fine and close that the molten resin tissue around the strengthening part 33 becomes, and is melted resin filling and support around the strengthening part 33.
Molten resin is because viscosity is very large, even exert pressure, its pressure can not be delivered to the bottom immediately yet, but slowly transmission, so, make pressure keep the stipulated time.
The 6th step 350, such as Figure 12 and shown in Figure 16, to two shelves 30 away from direction start pneumatic cylinder 30b, transfer shelf 30, thereby, shelf 30 from the two end portions of fixed part 33 from.If shelf 30 retreats, then between the molten resin (MT) of cavity 21 interior perfusions and shelf 30, occur transferring the space that produces because of shelf.
The 7th step 360, such as Figure 13 and shown in Figure 16, as making partition framework 24 enter into the operation that retreats the space that produces because of shelf 30, primer fluid cylinder pressure 24a makes partition framework 24 enter in the cavity 21 by bullport 26.Be disposed in the cavity 21 if cut off framework 24, the pressure support plate 26 that then cuts off framework 24 is disposed at the front of shelf 30.Afterwards, with the pressure that applied pressure is higher than the 1st time upper die 10 is pressurizeed.This moment, institute's applied pressure made upper die drop to bottom in the guide member 27.
If further improve the pressure that puts on molten resin (MT), then the molten resin of perfusion spreads because of pressure, be squeezed into and be formed in the space that cuts off framework 24 fronts and be full of, the both ends of strengthening part 33 bury fully in molten resin (MT).
On the other hand, where necessary, also can after the partition framework is set, fill molten resin in the space that after shelf 30 retreats, produces.
The 8th step 370, such as Figure 14 and shown in Figure 16, with 2 higher pressure of pressure that molten resin (MT) applied than the 2nd time, to molten resin (MT) the pressurization stipulated time and after making it to solidify, take out the article shaped of moulding and finish the formation of article shaped from lower mould 20.At this moment, for the resin that makes melting solidifies rapidly and is keeping top and lower mould 10, in the time of 20 pressure, make cooling water circulation in cooling jacket 40, in 50 and mould is cooled off, the molten resin (MT) of cavity 21 interior perfusions is solidified, wherein, when molten resin is solidified, (make upper die drop to the bottom of guide member 27 with the exert pressure higher than the pressure that puts on upper die 10, namely, the position that upper die is alignd with lower mould), thus make the molten resin that shrinks insufficient section because of molten resin (MT) force to be filled in the cavity 21.
Through after the stipulated time, such as Figure 15 and shown in Figure 16, remove the pressure that puts on upper die 10, the article shaped of cavity 21 interior moulding is separated from lower mould 20, finish the moulding 380 (with reference to Figure 16) of pallet 200 (with reference to Fig. 1).
In addition, during the article shaped of in taking out cavity 21, solidifying, between article shaped and lower mould 20, apply air pressure, by air pressure, can take out easily, and bad article shaped does not occur.
In Figure 16, Reference numeral 390 is illustrated in the operation that makes molten resin curing, in order to improve curing rate upper die 10 and lower mould 20 is carried out the operation that water cooling is solidified rapidly molten resin.
On the other hand, as previously mentioned, shown in Fig. 1 b, pallet 200 shown in Fig. 1 a can form the pallet leg by the design cavity in lower mould 20, also can on the pallet 200 of finishing as shown in Figure 1a, utilize screw bolt and nut timber leg 201 to be installed and to be used as and load, transport, support and use pallet.
In sum, use in the pallet forming method in top load supporting of the present invention, the both ends of strengthening part 33 are supported securely by shelf 30, be supported under the state of shelf, be embedded in the molten resin, so, can accurately keep the interval of imbedding 33 of position and strengthening parts of the strengthening part 33 buried underground in the article shaped and the horizontal level of strengthening part, clearly guarantee the reliability of moulding pallet.
And, after the shelf 30 of support reinforcing parts 33 retreats, fill the space that produces because of the shelf handover with molten resin, do not need to form the hole that is communicated with strengthening part in the article shaped outside of moulding, so moisture content can not flow into or immerse in the irony strengthening part.
